Care Details
Ideal Sunlight Coverage:

Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; protect from harsh afternoon sun in hot regions; ensure adequate light indoors with supplemental grow lights if needed.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun
Rotate plants for even light exposure; use sheer curtains to filter intense sun; avoid placing in shaded corners.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly until it drains from the bottom; allow soil to dry between waterings; avoid overhead watering to prevent fungal issues.
Soil
well-draining, sandy loam with moderate organic content
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix of potting soil and perlite; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Prefers warm conditions (65–85°F / 18–29°C); thrives in heat but may require shade in extreme temperatures.
Monitor temperature extremes; adjust watering in heat; protect from frost.
Fertilizing
every 4–6 weeks during growing season with balanced liquid fertilizer
Fertilize lightly to avoid excessive foliage growth; apply after watering to prevent root burn; stop fertilizing in fall.
Propagation
Methods
Stem cuttings or seeds.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Keep moist and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (70–75°F / 21–24°C), humid, and bright indirect light.
Medium
Well-draining potting mix with perlite or sand.
Hormone
Rooting hormone is recommended for faster root development.
Timeline
Roots develop in 2–4 weeks; new growth appears in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; maintain high humidity with a plastic cover; keep out of direct sun.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushiness; cut above leaf nodes to encourage branching.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove spent flowers to prolong blooming.
Tools
Pruning shears, clean scissors.
Checklist
Sterilize tools; prune dead or damaged stems; remove spent flowers; shape the plant.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter).
Method
Remove plant gently; trim roots if necessary; place in a slightly larger pot with fresh soil; water thoroughly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and vigor.
Checklist
Choose appropriate pot size; prepare fresh soil mix; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; avoid wetting foliage.
How to Apply Water Properly
Water directly at the root zone, ensuring even moisture distribution; water early in the morning to minimize evaporation and fungal growth; ensure excess water drains away to prevent waterlogging.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure soil is loose and airy.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf scorch, or stunted growth in excessive heat; cold damage, leaf drop, or slowed growth in cold stress.
Cold Stress
Low temperatures slow growth and can cause leaf damage or death; frost is particularly harmful.
Solution: Move potted plants indoors during cold spells; use frost cloth for outdoor plants; ensure good air circulation to prevent cold pockets.
Hot Stress
Excessive heat can lead to wilting, flower drop, and reduced vigor; may require increased watering.
Solution: Provide afternoon shade; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during active growth; avoid winter feeding.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during the growing season; avoid fertilizing in winter.
